SPECIFICATION forming part of Letters Patent No. 299,367, dated May 27, 1884.

Application filed March 17, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, NIOKOLAS FINK, a citizen of the United States, and a resident of Edmore, Montcalm county, Michigan, have invented a Combined King-Bolt and Circle for Vehicles, of which the following is a specification.

The object of my invention is to construct in a simple and economical manner acombined king-bolt and circle or fifth-wheel for vehicles; and this object I attain as hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure l is a perspective View of the device, the parts being detached from each other; Fig. 2, a front View, Fig. 3 an end view, and Fig. 4 a plan view, of part of the device. I

A is a box which fits snugly to the axle w, and is secured thereto by clips a, or in any other suitable manner. This box has atubular projection, b, for the reception of the kingbolt 13, which can turn freely in the projection, but is confined vertically thereto by a nut, d, adapted to the threaded lower end of the bolt. The head F of the bolt is segmental, and bears upon a segmental projection, f, formed on the box A, and upon the beveled edge or periphery of the said segmental head F bears lugs g, which are beveled to conform to the said edge, and serve to guide the head and aid the nut cl in preventing vertical movement of the bolt. I

To a projection, G, on the head F is hung, by means of a pin, h, a bar, J, to which is secured, by clips 2', the lower portion of the spring K, which supports the front end of the I vehicle-body, the upper part of the spring being connected to said body in any suitable manner. The axle can turn freely on the kingbolt,the movement being steadied by the hearing of the segmental head F on the projection f, and by the guiding and retaining lugs g.

WVhen it is desired to detach the axle,the nut d is removed and the axle turned so as to free the head F of the bolt from the control of the lugs, thus allowing the body of the vehicle to be raised until the king-bolt is clear of the box A.

The device described, while serving the purpose of the ordinary fifth-wheel, is more compact and economical than the same, and possesses greater strength.

I claim as my inventiona The combination of the box A, having a tubular projection, 72, and bearingf, and the kingbolt 13, having a segmental head, F, with the guiding and retaining lugs g, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NIOKOLAS FINK.
